Pitt appeared on Late Night With Jimmy Fallon on Tuesday night to promote his new movie ‘World War Z’, which is released this Friday. Pitt plays the part of a former UN troubleshooter Gerry, in the apocalyptic horror film.

During the comedy skit the stars engage in a "conversation" high above the city about the new movie before Pitt challenges Fallon to something that's "never been done before."

The conversation started with small talk, "Jimmy? What are you doing up there?" "Yodeling … you?" "Same" -- before Fallon congratulated Pitt on World War Z.
